An Investigation of the Nature and Extent of Attenuation of 3.2-cm Radiation by Subtropical Precipitation

摘要

A quantitative study was made of the attenuation of 3.2-cm microwave energy by subtropical precipitation. Theoretical and practical aspects of the problem are considered. The empirical relationships between cloud and radar parameters are examined. Attenuation factors for 3.2-cm radiation are determined from data obtained from a dual-frequency radar system. Comparisons are made of the results obtained from the dual-frequency system with those from a single radar. (Author)
